    I have no idea how such giant animals and insects (2' wide dragonflies, 8' long centipedes etc) were possible. Oxygen content must have been alot higher in that early atmosphere. I do not see how any of them could survive in current conditions.

    It was a lot higher! So were the CO2 levels depending on the period.

    Despite her high oxygen usage, Hillary seems to be surviving, so maybe it would be possible..........:D
